|
|
* By popular demand, we define a struct to represent an expression.
|
|
* This will no doubt mutate as expressions become baroque.
|
|
*
|
|
* Currently, we support expressions like "foo OP bar + 42". In other
|
|
* words we permit a (possibly undefined) symbol, a (possibly
|
|
* undefined) symbol and the operation used to combine the symbols,
|
|
* and an (absolute) augend. RMS says this is so we can have 1-pass
|
|
* assembly for any compiler emissions, and a 'case' statement might
|
|
* emit 'undefined1 - undefined2'.
|
|
*
|
|
* The type of an expression used to be stored as a segment. That got
|
|
* confusing because it overloaded the concept of a segment. I added
|
|
* an operator field, instead.
